The bottleneck is a common defense pattern. The board fragment below shows a position where the vertical player (red) wants to connect to the bottom, but is being hindered by blue in a bottleneck formation.
The bottleneck formation invariably leads to a ladder situation. Red gets ladders in both directions.
